# terraform-plan-comment

GitHub Action to post the output of `terraform plan` to a pull request comment.

## Features

- Generate a structured, "markdown-native" representation of the plan

  - Obtain a high-level overview via foldable sections

  - Do not lose _any_ information compared to the output of `terraform plan`

- Post the plan to pull requests as a "sticky comment"

- Run as a "native" JavaScript action rather than launching a Docker container

- Use with or without the Terraform wrapper script provided by

  [hashicorp/setup-terraform](https://github.com/hashicorp/setup-terraform)

## Usage

```yaml

- name: Setup terraform

  uses: hashicorp/setup-terraform@v3

- name: Initialize

  run: terraform init

- name: Plan

  run: terraform plan -out .planfile

- name: Post PR comment

  uses: borchero/terraform-plan-comment@v2

  with:

    token: ${{ github.token }}

    planfile: .planfile

```

### Example Comments

Collapsed



Expanded



## Parameters

This action provides a few input parameters that allow for customization:

### `token` (required)

Required input parameter to access the GitHub API for posting a pull request comment. Can be provided as

`${{ github.token }}`, `${{ env.GITHUB_TOKEN }}` or some personal access token with appropriate permissions.

If using the workflow-provided token, make sure that your workflow/job has write-permissions to pull requests.

### `planfile` (required)

The path to the planfile generated by `terraform plan` which holds the information about which changes ought to be

applied.

### `terraform-cmd`

The command to execute to call the Terraform binary. Defaults to `terraform`. You likely don't need to augment this

unless `terraform` cannot be found in the `PATH`.

### `working-directory`

The directory where the Terraform binary ought to be called. Defaults to `$GITHUB_WORKSPACE` and _must_ be specified if

`terraform init` has been run in a different directory. Should be specified relative to `$GITHUB_WORKSPACE`.

> [!IMPORTANT]

> `planfile` must be specified relative to the working directory.

### `header`

The header that is used for the pull request comment posted by this action. Changing the default allows to distinguish

multiple Terraform runs: each sticky pull request comment is identified by its header.
